PACKING-WASHER.

SPECIFICATION forming part of Letters Patent No. 787,160, dated April11, 1905.

Application filed November 2l, 1904. Serial No. 233,688.

le it known that l, UnAnLns Erre, a citizen ofthe United States,residing at St. Louis, Missouri, have invented a` certain new and usefulImprovement in Packing-'ashers. of which the following is a full, Qlear,and exact description, such as will enable others skilled in the art towhich it :wpertains to make and use the saine, reference being had tothe aC- connianying drawings, forming part of this spi'ailication, inwhich Figure l is an end view of two beams, showing my inventionapplied. Fig. Q is a top plan view of my improved washer, and Fig. I),is a cross-sectional view on the line 3 3 of liig. L).

This invention relates to washers, and particularly to the class knownto the trade as "pat-king or spacing washers.

lleretoforc washers utilized between beams for car-sills, bridgeconstruction, and the like have generally been constructed of a solidcasting the size and weight of which was a considerable diszulvantage,owing to the amount of metal employed, and, further, due to the factthat said washers were generally made of cast-iron. so that they becameeasily broken in transit, were ui'isightly in appearance, their weightadding considerable to their ultimate cost, due to transportation, oto.

lt is the purpose of my invention to make a light, durable, andeflicient packing-washer which will possess substantially the samecrosssectional area throughout, so that the washer will not only belight, but owing to the fact that it can be readily annealed or madeinto a malleable casting will be considerably stronger than the solidcasting heretofore used and which required so much more metal in itsconstruction. As a result l lind that while the washer constructed inaccordance with my invention possesses considerably more strength thanthe washers heretofore employed they are not liable to break and agreater number of washers per pound may be provided` thus reducing thecost of freight per given number, as well as reducing the weight of themetal on the car or bridge construction.

ln the form of washer illustrated in the accompanying drawings, Yldesignates a tubular body portion, preferably cylindrical and havingprojecting outwardly from its respective ends web portions 2 and 3,which are connected at their peripheries by spacing-webs a, arranged inmultiple and preferably bcingsemicylindrical in cross-section, the flatfaces 5 being turned outwardly, while the inclined portions areinturned.

lnasmuch as this washer is particularly designed to be placed betweentwo wooden beams, as shown in Fig. l, it will be obvious that moisturedue to rain, snow, &c., will readily pass otl the washer, owing to thecurved portions against which it would strike, so that the moisture willnot be held in contact with the wood to cause rot, deterioration, etc.Attention is alsooalled to the fact that by providing the walls of thecylindrical body portion l and the webs 2 and 3 of the same thick nessthe washer may be readily annealed, so that the malleable castingresulting from such treatment will possess the maximum amount ofstrength with a minimum weight.

Having thus described my invention, what l claim as new, and desire tosecure by Letters Patent, is"s l. A malleable washer, comprising amalleable casting, including a tube havingl parallel webs, one at eachend thereof, and integral braces between said webs and spaced away fromthe tube; substantially as described.

2. A washer, comprising a cylindrical body portion, outwardly-extendingwebs, one at each end of the body portion, and a plurality of websdisposed around the peripheries of the lirst-named webs and connectingthem; substantially as described.

3. A malleable washer, comprisinga central tubular body portion,outwardly-extending webs connected to the body portion, and websconnecting t'ne lirst-named. webs, said connecting-webs beingsubstantially semicircular in cross-section with their flat facespresented toward the peripheriesof the lirst-named webs; substantiallyas described.

ln testimony whereof l hereunto allix my signature, in the presence oftwo witnesses, this 17th day of November, i90-l.
